STORE-=SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 35 5,341, dated January 18, 1887. Application filed September 20, 1856. Serial No. '2l-i,014. (No model.)

To (LZZ whom it may concern:

Be it known that I, BENJAMIN O. ALGIE, a citizen of the United States, and a resident of Ogdensburg, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Store-Service Apparatus; and I do hereby declare that the fol lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is an illustration of the two end brackets of my store-service apparatus, the middle portion of the track-wire being omitted. Fig. 2 is a perspective view, on an enlarged scale, of one of the brackets. Fig. 3 is a section through the spring-pulley upon which winds the string that controls the propelling cord, and Fig. 4 is a top view of the outer end of the bracket-arm.

Like letters of reference indicate corresponding parts through the figures.

My invention has relation to store-service apparatus; and it consists in the improved construction and combination of parts which constitute certain improvements upon the ap paratus for which Letters Patent of the United States, No. 342,557, were granted to me June 24, 1885, as will be hereinafter fully set forth.

The object of my invention is to add to the apparatus covered by the abovementioned patent a hinged bracket provided with an adjustment-screw for the purpose of securing the wire track to said bracket and keeping it taut; also, to provide automatic means. of gradually stopping the carriage at the ends of its route, the same means serving to hold the carriage at the starting point till as much pressure is exerted upon it by the propellingcord as will give it an initial velocity nearly sufficient to send it to the other end of its route, thus avoiding an excess of downward strain upon that portion of the track to which the propelling-cord is attached.

Another object is to replace the spiral spring of my old device by a spring-pulley, which I compactly attach to the bracket.

Referring to the accompanying drawings, A representsthe securing-plate, with its hingeears, to which the inner ends, B, of the bracket I are secured by the pintle G. This bracket consists of a U shaped portion, from one side of which extends said ends B and from the other side the curved arm D, which is arched near its inner end and bifurcated at its outer end. Through the sides ofthe U-shaped portion extends the adjustment-screw E, which has a swivel at its outer end, into which the end of the track-wire F is secured, and which keeps the wire from twisting when tightening. This screw serves to keep the wire taut, in order that the transit of the carriage X may be more rapid, and that the track-wire and stoppinglever may always be at the same distance apart and in the same plane. In the lower part of the U shaped portion, under the screw, isjournaled a spi'iiig-1: ulley, G, upon which is wound, by the helical spring H, thestring I, attached to the propelling-cord J. Y The loca tion, attachment, and operation ofsaid cord are fully set forth in my previous patent. From the junction of said string and cord depends the pull-rope K, the string passing from the pulley to said junction through the slot L.

Between the forks at the outer end of the arm D is hinged the stopping-lever M, and to the outside of each fork is hinged one end of a guide-wing, N, the other end of each wing being pivoted to said lever. These wings guide the upper wheel of the carriage to the stoppinglever, whose lower edge fits into the groove of said wheel. The inner end of the lever is arched to provide for holding the carriage still till the required pressure is exerted upon the propelling-cord to release it and start it for the other end of the track. (See dotted position, Fig. 1.) The inner end of said lever passes through the upper portion of the slot Lin the bracket, and is provided with a series of adj ustment-perforations for the attachment of a spiral spring, 0, which is secured to the bracket. This spring may be replaced by the weight P, or by the plate-spring Q, located between the arm and the lever, any one of which means would serve in increasing thepressure of thestopping-lever. The bracket being hinged to the securing-plate, provides, in connection with the adjustmentscrew, for always keeping the arm of the bracket in the same plane with the track-wire. It is obvious that this stopping device, with slight modifications, can be used with other forms of track.

Having thus fully described my invention, I claim- 1. In a store-service apparatus, the eornbi nation, with the track-wire, of a bracket consisting of a U-shaped portion, from one side of which extend two ends and from the other a curved arm, the front arm of said U-shaped portion being slotted, an adjustment-screw located in the rear arm of and projecting through said slot in the front arm of the U-shaped portion of said bracket, and a swivel upon the end of said screw.

2. In a store-service apparatus, the combination, with the track-wire and the propellingcord, of a bracket consisting of a U-shaped portion, from one side of which extend two ends and from the other a curved arm, the front arm of said U -shaped portion being slotted, a spring'pulley located in the lower portion of said U shaped portion of said bracket, and a string attached to said pulley and to the propelling-cord.

3. In a store-service apparatus, the combination, with the track-wire, ofa hinged bracket provided with a stopping-lever, the outer end of said lever being pivotally secured to the outer end of said bracket and the inner end provided with an upward curve or arch, and a grooved wheel upon said wire adapted to receive the lower edge of said lever.

4. In a store service apparatus, the combination, with the bracket, the track-wire, the propelling-cord, and the carriage, of a stopping-lever hinged by its outer end to an arm of said bracket and adapted to play in a slot at the inner end of said arm.

5. I11 a store-service apparatus, the combination, with the bracket, the track-wire, and the carriage, of a stoppinglever arched near its inner end, and means, substantially as described, for adjusting the downward pressure of the rear end of said lever.

6. In a store-service apparatus, the combination, with the bracket, the track-wire, and the stoppinglever, of a pair of wings attached to said bracket and lever.

7. In a store-service apparatus, the combination, with the bracket, the track-wire, and the carriage. of a stopping-lever pivoted at the outer end of said bracket, the rear end of which is provided with a series of holes and its intermediate portion with a curve or arch, and a spring, one end of which is secured to said bracket and the other end adapted to be engaged in either of said holes.

In testimony that I claim the foregoing as my own I have hereunto aflixed my signature in presence of two witnesses.

BENJAMIN G. ALGIE.
